Compact, rugged, and efficient, the MX401 Four-Channel Stereo Mixer from Rolls is a deceptively flexible analog audio mixer designed to make mobile sound setups and field recording hassle-free. The unit features four channels of XLR audio input and balanced stereo XLR outputs, with all XLR I/O featuring individual mic/line level selection. The MX401 also sports level control for each input channel, master gain control, an extra 3.5mm stereo output for headphones or as an aux send, and 15V of phantom power selectable for each input. Crucially, the MX401 can not only run off of the included 15 VDC power supply, but also on two common 9V alkaline batteries for completely mobile, outlet-free operation.
Elegant and Efficient I/O
- Four balanced XLR input channels with mic/line selection
- Level control and stereo pan control per channel
- Balanced stereo XLR outputs provide a stereo feed for monitors, PA system, or audio interface
- Selectable mic/line level for each XLR output
- Flexible unbalanced 3.5mm stereo output for headphones or record send
- Main output gain control with clip indicator
Flexible Power Options
The MX401 features two options for power, including a standard 15 VDC power supply (included) and the ability to run on two 9V alkaline batteries, placed in dedicated slots on the side. This ensures the MX401 can perform well in either a fixed position setup or a mobile setup, such as a field recording system. The unit also comes with selectable 15V phantom power, allowing individual selection of powered inputs.

The liner of the shirt can be unsightly with the neck worn open
Color: Black-polka Dots, Size: XX-Large
Be warned, if you get black, the shirt may actually be white inside. I ordered the black with white poka dots. The shirt was nice enough an would have looked okay completely buttoned to the top, however, if you wear the neck open like the model shows in the photos, the shirt is not like that. The shirt has an unsightly white liner which totally shows if you wear the neck unbuttoned at all.

The shirts run true to size and are very well made.
Color: Wine Red-polka Dots, Size: 3X-Large
I want the company COOFANDY and the customers who are considering buying these men's wrinkle free men's shirts for casual business wear, to know that the shirts are beautiful. The material is perfect, and they are made exceptionally well! One of the two shirts that I bought for my husband looks great on him. I had to buy one in a size 2x and one in a size 3x due to the reviews on Amazon's website, where so many of the reviewers stated that the size that they bought ran too small, while other reviewers said the shirt runs too large. My husband tried on the 2x, and it fit him perfectly, which was great because he always wears a 2x. The reason that I am returning them both is that these shirts are tuck-in shirts, and my husband only wears shirts that do not have to be tucked in, such as straight-bottom shirts. I showed him the picture of the shirt in the ad to prove that the models wore them out, not tucked in, but he said the style is wrong for wearing this shirt on the outside, and that he would not be able to wear it. I am so sorry, but I had to return them as he would not ever wear them. But I wanted you, COOFANDY, and your customers to know that the shirts are well worth the money and are just beautiful!

Perfect fit for my husband
Color: Army Green, Size: Large
Very thick but it's cool, comfortable, no shrinking when washed and no fading. Love this color and the quality of material for the price is top of the line. I will be ordering other colors. My husband really enjoys wearing this and it fits perfectly. Thank you for the excellent work.
